Problem- Chlorofluorocarbons released into the atmosphere from refrigerants and aerosol sprays were found to catalyze the decomposition of ozone leading to the formation of an ozone hole over the South Pole. The catalyzed reaction was found to have activation energy of 2.2 kJ/mol compared to activation energy of 17.7 kJ/mol for the uncatalyzed reaction.

1) By what factor is the decomposition rate constant increased in the catalyzed reaction at 300K
